Abstract
BACKGROUND Researches on the effect of hemodynamic stabilization on the implantation of conservative management for pediatric high-grade renal traumas are lacking. We aimed to assess the effect of maintaining the initial hemodynamic stability of pediatric patients with grades 3-5 renal trauma on the implementation of the conservative treatment and identify its defining factors. METHODS A prospective study was performed on pediatric patients with grade 3-5 renal traumas who presented to our hospital during July 2020-June 2022. Hemodynamically stable patients were compared with the unstable patients for clinical characteristics, hemodynamic stabilization, and rates of success of conservative treatment. RESULTS Forty-three patients were studied, including 26 boys and 17 girls. Of them, 28 (65.1%) patients presented with hemodynamic stability and 15 (34.9%) patients were unstable. Overall, 32 (74.4%) patients achieved and/or maintained hemodynamic stability for conservative management. There was a significant difference in blood pressure level at presentation (p < 0.001). The improvement of the hemodynamic parameters was significant per group and, in comparison (p < 0.001). The size of hematoma was significantly smaller in patients with hemodynamic stability (p = 0.023). Despite the longer (p = 0.033) hospital stay with conservative management, the rates of blood transfusion (p = 0.597) and hospital stay (p = 0.785) were not significantly different between both groups. The rates of nephrectomy and mortality were 14% and 0%, respectively. Blood pressure was independently associated with the achievement of maintained hemodynamic stability for conservative management (p = 0.022). CONCLUSIONS Hemodynamic stabilization seems to be effective and safe for implementing successful conservative management for pediatric patients with high-grade renal traumas. Blood pressure was the only independent factor of maintaining hemodynamic stability.

Abstract
Background There are persistent controversies about the outcomes and benefits of drainage of malignant ureteral obstruction by percutaneous nephrostomy (PCN). This study aimed to assess the predictors of the time-to-nadir (TTN) of serum creatinine (SCr) levels after drainage of bilaterally obstructed kidneys (BOKs) due to bladder cancer (BC) by PCN. Materials and methods This prospective nonrandomized study included patients with BOKs due to BC treated by PCN between April 2019 and March 2022. The primary outcome measure was TTN. Results Of the 55 patients with a median age (range) of 66 years (47-86 years), 32 (58.2%) had a normal nadir SCr and 23 (41.8%) had a high nadir SCr within 21 days after drainage of BOKs due to BC. High nadir SCr was associated with a higher mean age (p = 0.011) and lower body mass index (BMI, p = 0.043). However, patients with normal nadir SCr had a significantly shorter TTN (p = 0.023) and an increased mean SCr trajectory (p < 0.001) during TTN. In multivariate analysis, low urine output at presentation (p = 0.021) and high BMI (p = 0.006) were associated with longer TTN. However, the mean parenchymal thickness (p = 0.428) and laterality of drainage (p = 0.466) were not associated with the mean TTN and SCr normalization rates. According to the modified Clavien-Dindo classification, 8 cases of hematuria were managed conservatively (grade 2), and 2 cases of PCN slippage were repositioned using local anesthesia (grade 3). Conclusions Despite the safety of PCN for drainage of BOKs due to BC, more than 41% of the patients failed to have a normal nadir SCr. Predrainage low urine output and high BMI were associated with longer TTN. Laterality of drainage had no significant effects on the TTN and SCr trajectory.

Abstract
BACKGROUND Although the availability of related living donors (LDs) provides a better chance for receiving kidney transplantation (KT), the evaluation protocols for LD selection remain a safeguard for the LD's safety. These protocols are variable from one center to another, resulting in variable rates of decline of the potential LDs (PLDs). The decline of willing PLDs may occur at any stage of evaluation, starting from the initial contact and counseling to the day of operation. AIM To identify the causes of the decline of PLDs, the predictors of PLD candidacy, and the effect on achieving LDKT. METHODS A retrospective study was performed on the willing PLDs who attended our outpatient clinic for kidney donation to their related potential recipients between October 2015 and December 2022. The variables influencing their candidacy rate and the fate of their potential recipients were studied. Two groups of PLDs were compared: Candidate PLDs after a completed evaluation vs non-candidate PLDs with a complete or incomplete evaluation. A multivariate logistic regression was performed to assess the factors contributing to the achievement of PLD candidacy. RESULTS Of 321 willing PLDs, 257 PLDs (80.1%) accessed the evaluation to variable extents for 212 potential recipients, with a mean age (range) of 40.5 ± 10.4 (18-65) years, including 169 females (65.8%). The remaining 64 PLDs (19.9%) did not access the evaluation. Only 58 PLDs (18.1%) succeeded in donating, but 199 PDLs (62.0%) were declined; exclusion occurred in 144 PLDs (56.0%) for immunological causes (37.5%), medical causes (54.9%), combined causes (9.7%), and financial causes (2.1%). Regression and release occurred in 55 PLDs (17.1%). The potential recipients with candidate PLDs were not significantly different from those with non-candidate PLDs, except in age (P = 0.041), rates of completed evaluation, and exclusion of PLDs (P < 0.001). There were no factors that independently influenced the rate of PLD candidacy. Most patients who failed to have KT after the decline of their PLDs remained on hemodialysis for 6 mo to 6 years. CONCLUSION The rate of decline of willing related PLDs was high due to medical or immunological contraindications, release, or regression of PLDs. It reduced the chances of high percentages of potential recipients in LDKT.

Abstract
Background Numerous surgical techniques are available for the correction of isolated ventral congenital penile curvature (IVCPC). This study aimed to assess the outcomes and predictors of IVCPC treatment in adults using an incisionless plication technique. Materials and methods This prospective case series examined patients with IVCPC who were treated in our hospital between October 2017 and February 2020 using incisionless plication of the tunica albuginea (Essed-Schroeder technique) with a covering pair of absorbable sutures. The primary outcomes were successful correction (defined as a residual curvature ≤15 degrees) and patient satisfaction. Postoperative follow-ups were performed at 3, 6, and 12 months. Results A total of 23 patients were treated for IVCPC with a mean (range) age of 25.3 (18-31) years. Eighteen patients (78.3%) were single with cosmetic complaints, whereas the other 5 patients (21.7%) were married and presented with a difficult vaginal intromission. The mean (range) curvature, length, and operative time were 40 (30-50) degrees, 15 (10-19) cm, and 82 (65-100) minutes, respectively. Postoperative penile pain and numbness occurred in 13 patients (56.5 %) and 7 patients (30.4%) only within the first month, respectively. Palpable suture knots were reported in 15 patients (65.5%) without being bothersome up to 12 months. The postoperative means (ranges) of penile curvature and length were significantly different from that of the preoperative values at 3 (5 [0-20] degrees and 14.5 [9-18.5] cm), 6 (5 [0-20] degrees and 14.5 [9-18.5] cm), and 12 months (5 [0-30] degrees and 14.5 [9-18.5] cm; all p < 0.001). Age, preoperative penile curvature, penile length, postoperative pain, wound infections, and knot palpation insignificantly affected curvature recurrence. Seventeen patients (73.9%) were very satisfied with their surgical outcomes. Conclusions Incisionless plication of the tunica albuginea is effective and safe for the correction of IVCPC in adults with high success and patient satisfaction rates.

Abstract
BACKGROUND Preemptive living donor kidney transplantation (PLDKT) is recommended as the optimal treatment for end-stage renal disease.
AIM To assess the rate of PLDKT among patients who accessed KT in our center and review the status of PLDKT in Egypt.
METHODS We performed a retrospective review of the patients who accessed KT in our center from November 2015 to November 2022. In addition, the PLDKT status in Egypt was reviewed relative to the literature.
RESULTS Of the 304 patients who accessed KT, 32 patients (10.5%) had preemptive access to KT (PAKT). The means of age and estimated glomerular filtration rate were 31.7 ± 13 years and 12.8 ± 3.5 mL/min/1.73 m2, respectively. Fifty-nine patients had KT, including 3 PLDKTs only (5.1% of total KTs and 9.4% of PAKT). Twenty-nine patients (90.6%) failed to receive PLDKT due to donor unavailability (25%), exclusion (28.6%), regression from donation (3.6%), and patient regression on starting dialysis (39.3%). In multivariate analysis, known primary kidney disease (P = 0.002), patient age (P = 0.031) and sex (P = 0.001) were independent predictors of achievement of KT in our center. However, PAKT was not significantly (P = 0.065) associated with the achievement of KT. Review of the literature revealed lower rates of PLDKT in Egypt than those in the literature.
CONCLUSION Patient age, sex, and primary kidney disease are independent predictors of achieving living donor KT. Despite its non-significant effect, PAKT may enhance the low rates of PLDKT. The main causes of non-achievement of PLDKT were patient regression on starting regular dialysis and donor unavailability or exclusion.

Abstract
BACKGROUND Giant stones of the urinary bladder (GSBs) are rare and usually presented as case reports. We aimed to assess the clinical and surgical characteristics of GSBs and identify their predictors. METHODS A retrospective study of 74 patients with GSBs who presented between July, 2005 and June, 2020 was performed. Patients' demographics, clinical presentations, and surgical peculiarities were studied. RESULTS Older age and male gender were risk factors for the occurrence of GSBs. The irritative lower urinary tract symptoms (iLUTS) were the main presenting symptoms (97.3%). Most patients were treated with cystolithotomy (90.1%). Univariate analyses showed that solitary (p < 0.001) and rough surface (P = 0.009) stones were significant factors for occurrence of iLUTS as the presenting symptoms. Also, the severity of symptoms (p = 0.021), rough surface (p = 0.010) and size (p < 0.001) of stones, and farmer occupation (p = 0.009) were significantly associated with adherence of the stone to the bladder mucosa at surgery. In multivariate analysis, the rough surface (p = 0.014) and solitary (p = 0.006) stones, and concomitant ureteral stones (p = 0.020) were independently associated with iLUTS as the main presentation. However, the stone size and severity of iLUTS were the independently associated factors for adherence of GSBs to the bladder mucosa. CONCLUSIONS Solitary GSB, rough surface and the association with ureteral stones are independent risk factors for the occurrence of long-standing iLUTS. The stone size and severity of iLUTS were the independent predictors of adherence of GSBs to the bladder mucosa. Cystolithotomy is the main treatment, but it may be more difficult when there is bladder mucosa adherence.

Abstract
Background Despite the continuous update of guidelines for the management of kidney stones, the ability to predict a successful response to extracorporeal shockwave lithotripsy (SWL) remains a topic of research. This is due to the need to refine the decision making in the context of technological advancements and current pandemics. This study aimed to determine the predictors of stone-free rate (SFR) after single-session SWL in adult patients with a single kidney stone 10 to 20 mm in diameter. Materials and methods A retrospective review of the records of patients with a single kidney stone 10 to 20 mm in diameter was performed at a private SWL center from December 2019 to February 2021. Univariate and multivariate analyses were performed for stone- and patient-related factors, using the Student t and Mann-Whitney U tests for the quantitative variables and the Fisher exact and Pearson correlation tests for the qualitative variables. Results A total of 138 patients were eligible for this study, including 92 men and 46 women. The mean age was 38.6 ± 12.4 years, and the mean body mass index (BMI) was 25.9 ± 3.4 kg/m2. Four weeks after SWL, 120 patients (87%) were free of stones, and 18 (13%) needed further treatment. Univariate analyses showed that SFR was negatively correlated with increased BMI (p = 0.0001), maximum stone length (p = 0.0001), transverse diameter of the stone (p = 0.0001), number of shocks per session (p = 0.052), and Hounsfield unit (HU) (p = 0.0001). Multivariate analysis revealed that HU (p = 0.009), maximum stone length (p = 0.01), BMI (p = 0.000), and presence of double-J stent (p = 0.034) were independent risk factors for failure of single-session SWL in the treatment of kidney stones 10 to 20 mm in diameter. The estimated average cost per case was USD 450.5. Conclusions Increased HU, maximum stone length, BMI, and presence of double-J stents were independent risk factors for low SFR after single-session SWL for a kidney stone 10 to 20 mm in diameter. The cost of SWL remains an advantage in the private sector.

Abstract
BACKGROUND Serum creatinine trajectory (SCr-Tr) is a neglected prognostic tool for chronic and acute kidney injury. We aimed to assess the predictors of SCr-Tr during the time-to-nadir and serum creatinine (SCr) normalization rate after drainage, using percutaneous nephrostomy in patients with bilateral malignant ureteral obstruction. METHODS A prospective non-randomized study was performed on SCr-Tr in patients with bilateral malignant ureteral obstruction from August 2019 to March 2022. The primary outcome was SCr-Tr during the time-to-nadir. RESULTS This study included 102 patients with a mean age ± SD of 59.6 ± 14.7 years. SCr-Tr was non-linear with a mean ± SD (range) of 0.5 ± 0.4 (0.03-2.3) mg/dl/day. Multivariate analyses revealed that female gender (p = 0.016), body mass index (BMI; p = 0.005), and SCr at presentation (p < 0.001) were predictors of rapid SCr-Tr during the time-to-nadir. However, age (p = 0.008) and low urine output at presentation (p = 0.015) were associated with a lower SCr-Tr. In contrast, laterality of drainage (p = 0.544) and mean parenchymal thickness (p = 0.066) were not associated with mean SCr-Tr. Also, only the mean parenchymal thickness (p = 0.002) was a predictor of rapid SCr-Tr at ≥ 0.5 mg/dl/day. However, low BMI (p = 0.023) was associated with a high SCr normalization rate, while unilateral drainage (p = 0.045) was associated with a lower rate. CONCLUSIONS Female gender, low BMI, and SCr at presentation were predictors of rapid SCr-Tr during the time-to-nadir. Bilateral drainage was an independent predictor of SCr normalization rate, but not of rapid SCr-Tr. The mean parenchymal thickness was the only independent predictor for rapid SCr-Tr at ≥ 0.5 mg/dl/day.

Abstract
OBJECTIVES to assess the functional outcome of performing ureteric re-implantation to an angled short chimney in a modified spiral orthotopic ileal neobladder. PATIENTS AND METHODS From January 2018 to December 2020, 90 male patients with bladder cancer underwent radical cystectomy and spiral ileal neobladder reconstruction with a chimney. Patients were randomly divided in two groups according to the position of the chimney [straight and angled] to which the ureters will be implanted. Postoperative evaluation included clinical, laboratory, radiographic and urodynamic studies. RESULTS There were no perioperative deaths. The mean operative time for the procedure was 4.7 ± 1.2 h in group I and 4.9 ± 1.3 h in group II (p 0.456). No intraoperative complications occurred. Early postoperative complications occurred in 8 patients. In group I, according to the modified Clavien system, GII complication occurred in 2 (5%) patients in the form of DVT in 1 (2.5%) and surgical site infection in 1 (2.5%). GIIIa occurred in 3 (7.5%) patients in the form of wound dehiscence. In group II, GII occurred in 2 (4.8%) patients in the form of prolonged urinary leakage and myocardial infarction, each occurred in one patient. GIIIb occurred in 1 (2.4%) patient in the form of intestinal leak. Poucho-ureteral reflux occurred in 10 patients [3 (7.5%) in group I and 7 (16.8%) in group II (p 0.001)]. CONCLUSIONS The preliminary results of the right sided angled chimney during neobladder reconstruction are safe, acceptable, without an extra time to develop an anti-reflux technique and without an increased incidence of reflux.

Abstract
BACKGROUND Despite the documented effects of the coronavirus disease 2019 (COVID-19) on spermatogenesis, the reversibility of these effects is uncertain. We aimed to assess the changes of sperm quality between the infection and recovery phases of COVID-19 in reproductive-aged men. The semen quality of men with mild-to-moderated COVID-19 (defined by the degrees of symptoms and chest involvement on computed tomography) was studied during October, 2020-May, 2021 at our hospital. Two semen samples were analyzed at timings estimated to represent spermatogenic cycles during the infection and recovery phases of COVID-19. RESULTS A total of 100 patients were included with mean ± SD (range) age of 24.6 ± 3.3 (21-35) years. During infection, 33% of patients had abnormal semen quality. However, a significant reduction was found in this abnormality from 33 to 11% (P < 0.001) after recovery from infection. In a comparison of the two semen analyses, there were significant improvements in the mean values of sperm progressive motility (P =0.043) and normal morphology (P < 0.001). However, the mean sperm concentration showed a statistically insignificant increase (P = 0.844). CONCLUSIONS In reproductive-aged patients with mild-to-moderate COVID-19, the effects on seminal quality were recoverable, represented by significant improvements in the means of progressive sperm motility and normal morphology between the infection and recovery phases of COVID-19.

Abstract
There is a well-known relationship between malignancy and impairment of kidney functions, either in the form of acute kidney injury or chronic kidney disease. In the former, however, bilateral malignant ureteral obstruction is a surgically correctable factor of this complex pathology. It warrants urgent drainage of the kidneys in emergency settings. However, there are multiple controversies and debates about the optimal mode of drainage of the bilaterally obstructed kidneys in these patients. This review addressed most of the concerns and provided a comprehensive presentation of this topic from the recent literature. Also, we provided different perspectives on the management of the bilateral obstructed kidneys due to malignancy. Despite the frequent trials for improving the success rates and functions of ureteral stents, placement of a percutaneous nephrostomy tube remains the most recommended tool of drainage due to bilateral ureteral obstruction, especially in patients with advanced malignancy. However, the disturbance of the quality of life of those patients remains a major unresolved concern. Beside the unfavorable prognostic potential of the underlying malignancy and the various risk stratification models that have been proposed, the response of the kidney to initial drainage can be anticipated and evaluated by multiple renal prognostic factors, including increased urine output, serum creatinine trajectory, and time-to-nadir serum creatinine after drainage.

Abstract
BACKGROUND The 2015 Lancet Commission on global surgery identified surgery and anaesthesia as indispensable parts of holistic health-care systems. However, COVID-19 exposed the fragility of planned surgical services around the world, which have also been neglected in pandemic recovery planning. This study aimed to develop and validate a novel index to support local elective surgical system strengthening and address growing backlogs. METHODS First, we performed an international consultation through a four-stage consensus process to develop a multidomain index for hospital-level assessment (surgical preparedness index; SPI). Second, we measured surgical preparedness across a global network of hospitals in high-income countries (HICs), middle-income countries (MICs), and low-income countries (LICs) to explore the distribution of the SPI at national, subnational, and hospital levels. Finally, using COVID-19 as an example of an external system shock, we compared hospitals' SPI to their planned surgical volume ratio (SVR; ie, operations for which the decision for surgery was made before hospital admission), calculated as the ratio of the observed surgical volume over a 1-month assessment period between June 6 and Aug 5, 2021, against the expected surgical volume based on hospital administrative data from the same period in 2019 (ie, a pre-pandemic baseline). A linear mixed-effects regression model was used to determine the effect of increasing SPI score. FINDINGS In the first phase, from a longlist of 103 candidate indicators, 23 were prioritised as core indicators of elective surgical system preparedness by 69 clinicians (23 [33%] women; 46 [67%] men; 41 from HICs, 22 from MICs, and six from LICs) from 32 countries. The multidomain SPI included 11 indicators on facilities and consumables, two on staffing, two on prioritisation, and eight on systems. Hospitals were scored from 23 (least prepared) to 115 points (most prepared). In the second phase, surgical preparedness was measured in 1632 hospitals by 4714 clinicians from 119 countries. 745 (45·6%) of 1632 hospitals were in MICs or LICs. The mean SPI score was 84·5 (95% CI 84·1-84·9), which varied between HIC (88·5 [89·0-88·0]), MIC (81·8 [82·5-81·1]), and LIC (66·8 [64·9-68·7]) settings. In the third phase, 1217 (74·6%) hospitals did not maintain their expected SVR during the COVID-19 pandemic, of which 625 (51·4%) were from HIC, 538 (44·2%) from MIC, and 54 (4·4%) from LIC settings. In the mixed-effects model, a 10-point increase in SPI corresponded to a 3·6% (95% CI 3·0-4·1; p<0·0001) increase in SVR. This was consistent in HIC (4·8% [4·1-5·5]; p<0·0001), MIC (2·8 [2·0-3·7]; p<0·0001), and LIC (3·8 [1·3-6·7%]; p<0·0001) settings. INTERPRETATION The SPI contains 23 indicators that are globally applicable, relevant across different system stressors, vary at a subnational level, and are collectable by front-line teams. In the case study of COVID-19, a higher SPI was associated with an increased planned surgical volume ratio independent of country income status, COVID-19 burden, and hospital type. Hospitals should perform annual self-assessment of their surgical preparedness to identify areas that can be improved, create resilience in local surgical systems, and upscale capacity to address elective surgery backlogs.

Abstract
The simultaneous kidney transplantation and ipsilateral native nephrectomy for autosomal dominant polycystic kidney disease does not seem to be associated with increased rates of comorbidity and complications. This outcome can efficiently be achieved when the indication and surgical approach of native nephrectomy are properly justified.

Abstract
PURPOSE To identify the predictors of nadir serum creatinine (SCr) after drainage of bilaterally obstructed kidneys (BOKs) by different modes: double-J stent (JJ) versus percutaneous nephrostomy (PCN) and unilateral versus bilateral drainage. METHODS A prospective non-randomized study was performed on patients with BOKs and raised SCr during December 2019-November 2021. Relevant variables were studied for improvement and non-improvement and for benign and malignant underlying obstructions (BUO and MUO). RESULTS This study included 107 patients with BOKs including 68 (63.6%) males and 39 (36.4%) females. After drainage, 86 (80.4%) patients get improved, while 21 (19.6%) patients failed to reach a nadir SCr. Drainage by PCN was significantly higher in MUO, while JJ was significantly higher in BUO (p < 0.001). Also, bilateral drainage was a significant predictor of improvement in MUO (p = 0.03). In contrast, mode of drainage had no significant effect on improvement in BUO (p = 0.84), but bilateral drainage was a significant factor of rapid time to nadir (p = 0.02). Univariate analyses revealed no significant effects on the improvement in SCr from the studied variables, except the male gender (p = 0.01), old age (p < 0.001), MUO (p = 0.01), unilateral drainage (p < 0.001), and use of PCN for drainage (p < 0.001). By multivariate analysis, unilateral drainage (p = 0.01) and MUO (p < 0.001) were independent predictors of non-improvement in patients with BOKs. CONCLUSIONS Male gender, old age, MUO, unilateral drainage, and drainage by PCN were significant predictors of non-improvement in SCr after drainage of BOKs. However, unilateral drainage and MUO were the only independent predictors of non-improvement.

Abstract
OBJECTIVE The aim of this study is to compare the outcomes of right- and left-sided live donor nephrectomies using the inverted kidney transplantation technique for right live donor nephrectomy on transplantation. MATERIAL AND METHODS A retrospective review was done for the cases of live donor nephrectomy, either as open donor nephrectomy or laparoscopic donor nephrectomy between 2004 and 2019. Inverted kidney transplantation was used with right-sided grafts. The variables of the right- and left-sided live donor nephrectomies were compared. RESULTS There were 202 live donor nephrectomies including 71 (35.1%) open donor nephrectomies and 131 (64.9%) laparoscopic donor nephrectomies with 4 cases of conversion to open donor nephrectomy. There were 119 (58.9%) right-sided and 83 (41.1%) left-sided live donor nephrectomies with insignificantly different mean operative time (123 and 127 minutes; P=.09), mean warm ischemia time (82.3 and 84.5 seconds; P=.32), and mean blood loss (73 and 78 mL; P=.18), respectively. Inverted kidney transplantation was performed for 86% of grafts from right live donor nephrectomies. Discharge from hospital was on an average of 4.3 days postoperatively. There were only 3 complications (1 in right live donor nephrectomy and 2 in left live donor nephrectomies) with grade 2 according to Clavien-Dindo Classification. Incidence of delayed graft function (P=.09), transplant vein thrombosis (1 case in each group), 1-year graft survival rate (93.2% vs. 94.8%; P=.12), and 1-year serum creatinine levels (1.4 ± 0.3 vs. 1.3 ± 0.2; P=.09) revealed statistically insignificant differences. CONCLUSION Regardless of the surgical technique, the right live donor nephrectomy seems to be technically as safe as the left live donor nephrectomy for both the donors and the recipients. Using inverted kidney transplantation provided convenient extensions of graft's vessels to full length with no significant increased incidence of vascular thrombosis.

Abstract
OBJECTIVE The aim of this study was to assess the efficacy and safety of mirabegron as a medical expulsive therapy in patients with distal ureteral stones of 5-10 mm size. MATERIAL AND METHODS A prospective, comparative study included 96 patients with radiopaque distal ure- teral stones of 5-10 mm who were randomly allocated and treated by medical expulsive therapy in 2 groups from January 2019 to December 2020. Patients in group A received only ketorolac 30 mg/day for 5 days, then on demand. Patients in group B received mirabegron 50 mg/day for 4 weeks plus ketorolac 30 mg/day like in group A. The stone expulsion rate was the primary outcome. RESULTS There were no significant differences regarding age, gender, body mass index, laterality, degree of hydronephrosis, and stone size. After 4 weeks, stone expulsion rate was 52.1% for group A versus 89.6% for group B (P < .001). The median (range) of time to stone expulsion was 14 (13-23) and 7 (3-16) days for groups A and B, respectively (P = .004). The medians (range; interquartile range) of episodes of renal pain (1 (0-2; 1) vs. (0-2; 2); P < .001) and extra analgesic ampoules (1 (0-7; 4) vs. 0 (0-2; 0) vials; P < .001) were significantly higher in group A than those in group B, respectively. In multivariate analysis, only medical expulsive therapy (P <.001) and stone size (P < .001) were independent predictors of stone expulsion rate. CONCLUSION Mirabegron is an effective and safe medical expulsive therapy agent in patients with 5-10 mm distal ureteral stones.

Abstract
BACKGROUND Unilateral small-sized kidney is a radiological term referring to both the congenital and acquired causes of reduced kidney volume. However, the hypoplastic kidney may have peculiar clinical and radiological characterizations.
AIM To evaluate the clinical presentations, complications, and management approaches of the radiologically diagnosed unilateral hypoplastic kidney.
METHODS A retrospective review of the records of patients with a radiological diagnosis of unilateral hypoplastic kidney between July 2015 and June 2020 was done at Assiut Urology and Nephrology Hospital, Assiut University, Egypt.
RESULTS A total of 33 cases were diagnosed to have unilateral hypoplastic kidney with a mean (range) age of 39.5 ± 11.2 (19-73) years. The main clinical presentation was loin pain (51.5%), stone passer (9.1%), anuria (12.1%), accidental discovery (15.2%), or manifestations of urinary tract infections (12.1%). Computed tomography was the most useful tool for radiological diagnosis. However, radioisotope scanning could be requested for verification of surgical interventions and nephrectomy decisions. Urolithiasis occurred in 23 (69.7%) cases and pyuria was detected in 22 (66.7%) cases where the infection was documented by culture and sensitivity test in 19 cases. While the non-complicated cases were managed by assurance only (12.1%), nephrectomy (15.2%) was performed for persistent complications. However, symptomatic (27.3%) and endoscopic (45.6%) approaches were used for the management of correctable complications.
CONCLUSION Unilateral hypoplastic kidney in adults has various complications that range from urinary tract infections to death from septicemia. Diagnosis is mainly radiological and management is usually conservative or minimally invasive.

Abstract
We aimed to determine the impact of pre-operative isolation on postoperative pulmonary complications after elective surgery during the global SARS-CoV-2 pandemic. We performed an international prospective cohort study including patients undergoing elective surgery in October 2020. Isolation was defined as the period before surgery during which patients did not leave their house or receive visitors from outside their household. The primary outcome was postoperative pulmonary complications, adjusted in multivariable models for measured confounders. Pre-defined sub-group analyses were performed for the primary outcome. A total of 96,454 patients from 114 countries were included and overall, 26,948 (27.9%) patients isolated before surgery. Postoperative pulmonary complications were recorded in 1947 (2.0%) patients of which 227 (11.7%) were associated with SARS-CoV-2 infection. Patients who isolated pre-operatively were older, had more respiratory comorbidities and were more commonly from areas of high SARS-CoV-2 incidence and high-income countries. Although the overall rates of postoperative pulmonary complications were similar in those that isolated and those that did not (2.1% vs 2.0%, respectively), isolation was associated with higher rates of postoperative pulmonary complications after adjustment (adjusted OR 1.20, 95%CI 1.05-1.36, p = 0.005). Sensitivity analyses revealed no further differences when patients were categorised by: pre-operative testing; use of COVID-19-free pathways; or community SARS-CoV-2 prevalence. The rate of postoperative pulmonary complications increased with periods of isolation longer than 3 days, with an OR (95%CI) at 4-7 days or ≥ 8 days of 1.25 (1.04-1.48), p = 0.015 and 1.31 (1.11-1.55), p = 0.001, respectively. Isolation before elective surgery might be associated with a small but clinically important increased risk of postoperative pulmonary complications. Longer periods of isolation showed no reduction in the risk of postoperative pulmonary complications. These findings have significant implications for global provision of elective surgical care.

Abstract
BACKGROUND Preoperative SARS-CoV-2 vaccination could support safer elective surgery. Vaccine numbers are limited so this study aimed to inform their prioritization by modelling. METHODS The primary outcome was the number needed to vaccinate (NNV) to prevent one COVID-19-related death in 1 year. NNVs were based on postoperative SARS-CoV-2 rates and mortality in an international cohort study (surgical patients), and community SARS-CoV-2 incidence and case fatality data (general population). NNV estimates were stratified by age (18-49, 50-69, 70 or more years) and type of surgery. Best- and worst-case scenarios were used to describe uncertainty. RESULTS NNVs were more favourable in surgical patients than the general population. The most favourable NNVs were in patients aged 70 years or more needing cancer surgery (351; best case 196, worst case 816) or non-cancer surgery (733; best case 407, worst case 1664). Both exceeded the NNV in the general population (1840; best case 1196, worst case 3066). NNVs for surgical patients remained favourable at a range of SARS-CoV-2 incidence rates in sensitivity analysis modelling. Globally, prioritizing preoperative vaccination of patients needing elective surgery ahead of the general population could prevent an additional 58 687 (best case 115 007, worst case 20 177) COVID-19-related deaths in 1 year. CONCLUSION As global roll out of SARS-CoV-2 vaccination proceeds, patients needing elective surgery should be prioritized ahead of the general population.

Abstract
SARS‐CoV‐2 has been associated with an increased rate of venous thromboembolism in critically ill patients. Since surgical patients are already at higher risk of venous thromboembolism than general populations, this study aimed to determine if patients with peri‐operative or prior SARS‐CoV‐2 were at further increased risk of venous thromboembolism. We conducted a planned sub‐study and analysis from an international, multicentre, prospective cohort study of elective and emergency patients undergoing surgery during October 2020. Patients from all surgical specialties were included. The primary outcome measure was venous thromboembolism (pulmonary embolism or deep vein thrombosis) within 30 days of surgery. SARS‐CoV‐2 diagnosis was defined as peri‐operative (7 days before to 30 days after surgery); recent (1–6 weeks before surgery); previous (≥7 weeks before surgery); or none. Information on prophylaxis regimens or pre‐operative anti‐coagulation for baseline comorbidities was not available. Postoperative venous thromboembolism rate was 0.5% (666/123,591) in patients without SARS‐CoV‐2; 2.2% (50/2317) in patients with peri‐operative SARS‐CoV‐2; 1.6% (15/953) in patients with recent SARS‐CoV‐2; and 1.0% (11/1148) in patients with previous SARS‐CoV‐2. After adjustment for confounding factors, patients with peri‐operative (adjusted odds ratio 1.5 (95%CI 1.1–2.0)) and recent SARS‐CoV‐2 (1.9 (95%CI 1.2–3.3)) remained at higher risk of venous thromboembolism, with a borderline finding in previous SARS‐CoV‐2 (1.7 (95%CI 0.9–3.0)). Overall, venous thromboembolism was independently associated with 30‐day mortality (5.4 (95%CI 4.3–6.7)). In patients with SARS‐CoV‐2, mortality without venous thromboembolism was 7.4% (319/4342) and with venous thromboembolism was 40.8% (31/76). Patients undergoing surgery with peri‐operative or recent SARS‐CoV‐2 appear to be at increased risk of postoperative venous thromboembolism compared with patients with no history of SARS‐CoV‐2 infection. Optimal venous thromboembolism prophylaxis and treatment are unknown in this cohort of patients, and these data should be interpreted accordingly.

Abstract
Peri-operative SARS-CoV-2 infection increases postoperative mortality. The aim of this study was to determine the optimal duration of planned delay before surgery in patients who have had SARS-CoV-2 infection. This international, multicentre, prospective cohort study included patients undergoing elective or emergency surgery during October 2020. Surgical patients with pre-operative SARS-CoV-2 infection were compared with those without previous SARS-CoV-2 infection. The primary outcome measure was 30-day postoperative mortality. Logistic regression models were used to calculate adjusted 30-day mortality rates stratified by time from diagnosis of SARS-CoV-2 infection to surgery. Among 140,231 patients (116 countries), 3127 patients (2.2%) had a pre-operative SARS-CoV-2 diagnosis. Adjusted 30-day mortality in patients without SARS-CoV-2 infection was 1.5% (95%CI 1.4-1.5). In patients with a pre-operative SARS-CoV-2 diagnosis, mortality was increased in patients having surgery within 0-2 weeks, 3-4 weeks and 5-6 weeks of the diagnosis (odds ratio (95%CI) 4.1 (3.3-4.8), 3.9 (2.6-5.1) and 3.6 (2.0-5.2), respectively). Surgery performed ≥ 7 weeks after SARS-CoV-2 diagnosis was associated with a similar mortality risk to baseline (odds ratio (95%CI) 1.5 (0.9-2.1)). After a ≥ 7 week delay in undertaking surgery following SARS-CoV-2 infection, patients with ongoing symptoms had a higher mortality than patients whose symptoms had resolved or who had been asymptomatic (6.0% (95%CI 3.2-8.7) vs. 2.4% (95%CI 1.4-3.4) vs. 1.3% (95%CI 0.6-2.0), respectively). Where possible, surgery should be delayed for at least 7 weeks following SARS-CoV-2 infection. Patients with ongoing symptoms ≥ 7 weeks from diagnosis may benefit from further delay.

Abstract
Objectives: To compare the efficacy, complications, and costs of percutaneous nephrolithotomy (PNL) and extracorporeal shock wave lithotripsy (SWL) in the treatment of a 20 to 30 mm single renal pelvic stone with a density ≤1000 HU. Patients and Methods: Eighty patients were prospectively randomized to receive either PNL or SWL during May 2017 to April 2019. The relevant demographic and clinical characteristics were compared. Results: The mean age in the PNL and SWL groups was 43.25 ± 15.16 and 44.18 ± 12.08 years, respectively. The mean stone sizes were 25.2 ± 3.9 and 24.6 ± 2.3 mm, respectively. The stone-free rate (SFR) was significantly different after the primary procedures (92.5% vs 37.5%, respectively; p < 0.04), but it was comparable after 3 months (97.5% vs 90%, respectively; p = 0.723), with a higher rate of auxiliary procedures after SWL (p = 0.017). On multivariate analysis, stone density was the only significant variable for the SFR in the SWL group (p = 0.004). Complications occurred in 27.5% and 22.5% of cases, respectively (p = 0.796). The mean costs of SWL (650.23 ± 424.74 United States Dollars [US$]) were significantly lower than those of PNL (1137.65 ± 224.43 US$; p < 0.0001). Conclusions: The SFRs for PNL and SWL were not significantly different after 3 months in the treatment of a 20 to 30 mm single renal pelvic stone with ≤1000 HU, although PNL provided a significantly higher rate after its primary procedure. SWL was significantly less costly, but it mandated a significantly higher number of auxiliary procedures than PNL.

Abstract
Background
Testicular ectopia is defined as a testis which is located away from the normal pathway of testicular descent and outside its ipsilateral hemiscrotum. Controversies have been raised about considering the abdominal and inguinal ectopic testes as undescended ones. Our purpose was to review our center’s experience with the diagnosis and management of testicular ectopia focusing on the inguinal ectopic testis. Retrospectively, we studied the clinical and surgical characteristics of a case series of testicular ectopia which was managed in our center during July 2001–June 2016.
Results
Out of 1132 patients with undescended testes, 44 cases (3.9%) had testicular ectopia. Twenty-three cases (mean age = 5.15 ± 5.79 years) fulfilled the criteria of inguinal ectopic testis. Clinically, testes were relatively mobile and superficial. Surgically, they were located in the superficial inguinal pouch, had relatively long spermatic cords, and commonly had average rather than small sizes. The other ectopic 21 cases (mean age = 10.56 ± 6.92 years) were perineal, anterior abdominal wall, femoral, prepubic, and transverse testes in 7 (33.3%), 4 (19%), 4 (19%), 3 (14.3%), and 3 (14.3%) cases, respectively. Congenital inguinal hernia was the commonest associated anomaly (22.7%). All cases were treated surgically with only 1 case of testicular atrophy (2.3%).
Conclusions
Testicular ectopia is rare with relatively delayed presentations. Different anatomical sites have been reported including the superficial inguinal pouch and anterior abdominal wall with variable complexities and controversies. The inguinal ectopic testis is the most controversial, but it might be characterized from other entities based on certain clinical and surgical criteria.

Abstract
Background
End-stage renal disease and loin pain are prevalent nephrourological topics with unfavorable reputations among populations. We aimed to present our center’s experience with the cases of phobia of renal failure in relation to loin pain.
Methods
It is a retrospective study of phobia of renal failure among the patients who presented with loin pain to our center between July 1991 and June 2017. Description of perception of renal failure risk was guided by the modified Common Sense Model of Illness Representation.
Results
Of more than 64, 000 patients who presented with loin pain, only 78 patients (0.12%) had phobia of renal failure. Mean age ± SD (Range) was 41.12 ± 9.58 (23–60) years. Sixty-four patients (82.1%) expressed directly fear of renal failure. Physical examination and investigations revealed no risks of renal failure in all patients. High percentages of phobia of renal failure were associated with the female gender (73.1%), the presence of a relative patient with renal failure (83.3%), and low socioeconomic levels: education (89.7%), residential (75.6%), and economic status (88.5%) levels. The modified Common Sense Model of Illness Representation revealed predominant emotional representations and unreal cognitive domains with altered perception of renal failure risk.
Conclusions
Phobia of renal failure is very rare. It is a consequence of the altered perception of risk of renal failure due to unconscious attribution of loin pain to renal failure. Female gender, the presence of a relative with renal failure, and low socioeconomic levels could be suggested as risk factors for phobia of renal failure.

Abstract
OBJECTIVES To present our center's experience in the management of adrenal myelolipoma in the context of shifting from the open to the laparoscopic adrenalectomy approach. MATERIALS AND METHODS A retrospective search of our center's records was done for reported cases of adrenal myelolipoma during the period July 2001-June 2016. All the cases with histopathologically-documented adrenal myelolipoma diagnosis were included. Relevant demographic and clinical variables were studied with a comparison between the open and laparoscopic approaches. RESULTS Of more than 82,000 urological surgeries, 238 adrenalectomies were done with only 22 cases of myelolipoma that had a mean age and body mass index of 52.4 ± 10.3 years and 30.23 kg/m2, respectively. The main clinical presentation was accidental discovery. The largest dimension of tumors varied from 6 to 16 cm. Computed tomography described a characteristic picture of hypodense heterogeneous adrenal tumors in all cases, while magnetic resonance imaging was indicated for malignancy suspicion in only 5 cases. Adrenal tumor markers were normal in all cases. Open and transperitoneal laparoscopic adrenalectomies were used in 14 and 8 cases, respectively. The latter approach was insignificantly advantageous in the need for blood transfusion, postoperative pain degree, need for analgesia, and hospital stay duration (p = 0.22). Histo-pathological examination revealed benign adipose tissue and myeloid cells and confirmed the diagnosis of adrenal myelolipoma in all cases. CONCLUSIONS Adrenal myelolipoma is a rare non-functioning benign tumor. Laparoscopic excision seems to be a promising alternative approach to the traditional open adrenalectomy, even in the context of large tumors and obesity.

Abstract
Abstract
Background
Giant hydronephrosis is rare with a controversy about the complete loss of renal functions. Our objective is to present our center’s experience with the management of cases of clinically visible giant hydronephrosis considering the potential residual functions. Our study is a retrospective case series of clinically visible giant hydronephrosis which was managed during the period July 2001–June 2016. Demographic and clinical variables were studied with specific considerations to the potential residual functions.
Results
Of more than 82,000 urological interventions, only 47 cases (0.057%) were operated upon for clinically visible giant hydronephrosis. Group 1 included 21 patients (mean age = 50.43 ± 13.71 years) who were treated initially by nephrostomy tube, and group 2 included 26 patients (mean age = 42.96 ± 15.16 years) who were treated primarily by nephrectomy. The main clinical presentation was abdominal distention (61.7%), while 13 patients (27.7%) were unaware of the swellings. The commonest underlying causes of hydronephrosis were urolithiasis (68.1%) and bilharzial ureteral strictures (23.4%). The contralateral kidney was diseased in 22 cases (46.8%) including the bilateral clinically visible hydronephrosis in 7 cases (15%). Indications of placement of a nephrostomy tube included uremia, infections, and evaluation of renal functions, where 5 cases of group 1 regained significant split function ranged 14–33%.
Conclusions
Clinically visible giant hydronephrosis is an extreme form of renal dilatation with different etiologies such as urolithiasis and bilharziasis. Initial placement of a nephrostomy tube may save significant residual functions in these kidneys.

Abstract
INTRODUCTION Unintentional self-inflicted injuries mainly refer to those injuries which are inflicted by the patient himself with benign intentions. In urology, they may vary and result in significant morbidities. PATIENTS AND METHODS A retrospective search of our patients' data records for the reported cases of patient's side-inflictor urological injuries during the period July 2006 - June 2016 was made. Each case was studied for age, gender, primary diagnosis, injury inflictor, involved organ, motivating factor, mechanism, diagnosis, management, and final outcome. RESULTS Of more than 55,000 urological procedures, 26 patients (0.047%) were involved in unintentional patient's side-inflictor urological injuries. The age range was 8-76 years and included 23 males and 3 females. Fifteen patients (57.7%) had urological disorders before the injury. They could be differentiated into direct organ involvement injuries (53.8%) and catheter involvement injuries (46.2%). External male urogenital organs were involved in 69.3% of cases which were diagnosed on physical examination. The inflictor of the injury was the patient himself, a relative, and another patient in 73.1, 19.2, and 7.7% of cases, respectively. Motivating factors were relief of painful conditions (34.6%), psychiatric disorders (38.5%), and sexual purposes (27%). Final outcomes were short-term harm, long-term harm, and permanent disability in 50, 11.5, and 38.5% of cases, respectively. CONCLUSION Unintentional patient's side-inflictor urological injuries are very rare events and mainly involve the external male urogenital organs under different motivating stressors. They could be differen-tiated into direct organ and catheter manipulation injuries with variable final outcomes from mild short-term harms to permanent disabilities.

Abstract
Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency-Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research.

Abstract
INTRODUCTION Surgical fires are unique topics that belong to surgical never events and deserve urological attention. MATERIALS AND METHODS A retrospective search of our hospital records was done for the states of electrosurgical never events in the period from July 2001 to June 2016. The included events were classified according to the site of occurrence in relation to the patient's body and possibilities of human involvement. The events were studied for the type, extent, damages, personnel involvements, complications, and management. RESULTS Of more than 82,000 urological interventions, 18 cases (0.022%) of electrosurgical never events were detected. Four subcategories were differentiated: electrosurgical theater fires (33.3%), electrosurgical contact skin burns (38.9%), electrosurgical internal injuries (16.7%), and electrocutions (11.1%). Electrosurgical theater fires included 3 ignition fires with fire skin burns and 3 device explosions. Fires only occurred with the use of alcoholic skin disinfectants. Contact skin burns resulted from inadvertent direct electrosurgical contacts, with 2 burns on the back, 3 burns on the lower limbs, 1 burn at the penile shaft, and 1 burn at the suprapubic region. Only 1 case of contact skin burn required plastic surgery. Electrosurgical internal in-juries involved the intestine, spleen, and urethra and were followed by major complications. Electrocutions involved a doctor and a patient with multiple bone fractures in the former. CONCLUSION Urological electrosurgical never events are very rare incidents and were differentiated into 4 clinical subcategories. Human involvements varied from absence to major devastating complications. Reduction of these events depends on the adjusted use of electricity-based armamentarium.

Abstract
BACKGROUND To compare the results of urethral anastomosis to a button hole and to the lowest part of the anterior suture line during orthotopic neobladder substitution. METHODS From January 2012 to December 2015, 87 consecutive male patients with invasive bladder cancer underwent radical cystectomy and Hautmann ileal neobladder. Patients were randomly divided into two groups; group I (44 patients), the outlet was created as a button-hole at the most dependent part of the pouch, group II (43 patients), the lowest 1 cm of the anterior suture line of the pouch was left open as an outlet. Patients were randomly assigned to either group using computer-generated random numbers (JMP, Version 12.0.1; SAS Institute, Cary, NC, USA) via a sealed envelope. The functional outcomes of both groups were compared especially at the urethro-enteric anastomosis. RESULTS There were no intraoperative complications. Early postoperative complications occurred in 9 patients (5 in group I and 4 in group II, p = 0.484). Prolonged urinary leakage persisted for 11 and 14 days in 2 patients in group I and 10 and 16 days in 2 patients in group II. Delayed postoperative complications occurred in 11 patients (5 [12.5%] in group I and 6 [15.6%] in group II) (p = 0.711). Three patients developed urethro-enteric strictures (2 in group I and 1 in group II) (p = 0.571). CONCLUSION The "non-hole" technique of urethral anastomosis was not associated with a significant increase in the complication rate when compared to the commonly performed "hole" technique.

Abstract
OBJECTIVE Presentation of our center's experience in the management of intracorporeally-retained urological surgical items. MATERIALS AND METHODS Retrospective search of our center's data for cases of retained surgical items during the period July 2006 to June 2016. Each case was studied for the demographic and clinical variables including types, presentation, and management. RESULTS Out of more than 55,000 different urological interventions, only 39 cases (28 males and 11 females) had retained surgical items. Urolithiasis-related urological subspecialties were more involved than others. Forgotten items and technically-retained items occurred in 38.5 and 61.5% of cases, respectively, and were immediately discovered or discovered up to 10 years later. Material types were textiles, biosynthetics, and metallics in 31, 51, and 18%, respectively. Possible predisposing factors included complex surgeries, emergent intraoperative events, and extra approaches. Occurrences of retained surgical items before and after implemented corrective actions were 74.6 and 25.4%, respectively. All the final outcomes were either short- or long-term harm without deaths, organ losses, or permanent disabilities. CONCLUSION Retained urological surgical items are surgical never events that result from forgetfulness or technical surgical human errors. Their sequels can be potentially fatal, but they are preventable and can be significantly reduced.

Abstract
INTRODUCTION Surgical never events are preventable harmful non-intentional human errors. Urology is a common surgical specialty for their occurrence. PATIENTS AND METHODS A retrospective search of our center's data was done during the period 2006-2016 for surgical never events. Each included case was studied for the primary diagnosis, procedure, and subspecialty, never event type and timing, needed extra-interventions, urologist/procedure proportioning, outcomes, and possible underlying causes of the event. RESULTS Of more than 55,000 different urological interventions, 61 patients were involved in never events. Wrong procedures represented 75% of the never events, and endourology and urolithiasis subspecialties were more often involved. The main detectable underlying factor was the disproportion between the levels of the procedure class and the qualification of the urologist (41%). Thirty-four cases had extra-procedures. The short-term harm effect represented the final outcome in 42% of all events. Death, permanent organ loss, and long-term harm represented 20, 15, and 23%, respectively. CONCLUSION Urological surgical never events are rare, but their final outcomes could be catastrophic, even leading to death.

Abstract
OBJECTIVES The study aimed to present our center's experience with long-standing urethral stones in male children with normal urethra. MATERIALS AND METHODS Retrospective search of our center data was done for the cases of long-standing urethral stones with normal urethra in male children during the period July 2001 - June 2016. Demographic and clinical data were studied. RESULTS Of more than 54,000 urolithiasis procedures, 17 male children (0.031%) were operated for long-standing urethral stones with normal urethra. In 14 cases (82.4%), residence was rural and parental education levels were low or none. All children were regularly prompted voiding with a history of difficulty or dysuria. All the stones lodged in the posterior urethra with an approximate mean duration of 2 months. The mean stone size of 11.29 ± 3.88 mm and rough surfaces in 88.2% of cases represented the main predisposing factors. Major complications included rectal prolapse in 1 case and vesicoureteral reflux in 3 cases. Endoscopic push-back was followed by disintegration in 76.5% or cystolithotomy in 17.7%, while it failed in 1 case that was treated by cystolithotomy. CONCLUSIONS Long-standing urethral stones in male children with normal urethra are very rare misdiagnoses. Stone topography and sociocultural factors predisposed to their lodgments and negligence. Endoscopic treatment is the best approach.

Abstract
OBJECTIVE The aim of this work is the presentation of a case of isolated renal hydatid cyst with novel findings and an unusual surgical scenario. CLINICAL PRESENTATION AND INTERVENTION A 54-year-old female patient presented with left loin pain and a palpable left renal mass. Imaging described a well-demarcated left renal cystic lesion with a double-layer wall. Radical nephrectomy was performed due to the possibility of malignancy. On retrograde revision, the double-layer wall represented the detached germinative membrane of a hydatid cyst that was confirmed by histopathology. CONCLUSION Isolated renal hydatid cyst could be misinterpreted as a renal tumor. It should be considered in the differential diagnosis of renal cystic lesions.
